Title: Out of memory when changing from one ogl windows to another.
Post by: Melssj5 on September 09, 2008, 04:39:47 pm

Hi I ran my Flier Match and fixed some bugs when I tested it:

Machine 1: Server
Machine 1: Client 1
Machine 1: Client 2

I had the ran well, but when I press alt+tab and changed from one OpenGL fullscreen client to the other I got an exceptio that it runs out of memory. I cant post the exception now becausse I forgot my pen drive at home.  :-[

It seems to be out of video memory becausse is not the typical message when running of of ram memory. I will post the exception tomorrow but I post this today becausse maybe someone has an idea anout how to fix it.

Yes, you are running out of video memory. The only time when i experienced something like this was on a PCI based GeForce8500GT that i'm using for testing from time to time. Anyway...are you calling dispose() on the used framebuffer? Is this the OpenGL- or the AWTGLRenderer?

in on the OpenGL at fullscreen. I am not calling to dispose. I am not exiting my application. Just using alt+tab to change from one ogl fullscreen to another. I always did it without problems with my actual hardware.

I see...is that an AGP based system? Maybe the AGP memory size configured in the BIOS is too small. Which graphics hardware is that?

Have you checked the AGP memory setting in the BIOS? Or maybe AGP texturing is disabled for some reason by the driver. Is this Windows or Linux?

Windows XP, sp2.

I have not changed anything in the bios, and it never appeared the problem until now. I will check the bios tomorrow to check if that helps.

On NVidia cards, you can enable a kind of NVidia Desktop Booster-Whatever-Thingy that eats memory for breakfast. You should check that too. Sadly, i forget the correct name of it, but i think you'll recognize it, if you see it.

mmm now that I remember I changed the driver with an older to be able to use some stereoscopic glases. Maybe thats the problem, I remove it and put another one after that but maybe is not the lastest driver. I will check that too.

BTW: JPCT looks too bad using stereo glasses!
